BUILDING-BLOCK.

Speoication of Letters Patent.

Patented Nov. 24.-, 1914.

Application filed August 15, 1913. Seria! No. 784,982.

To all whoma't may concern v Be it known that we, ADELBERT SmNNER and FRANK EWING, citizens of the United States, residing at Lents, in the county of Multnomah and State of Oregon, have 1nvented new and useful Improvements in Building-Blocks, of which the following 1s a specification.

The invention relates to building blocks, and has for its primary object to provide a block of this character wherein the same is of novel form and is materially reinforced so as to give strength thereto and to render it durable.

Another object of the invention is the provision of a building block wherein the body thereof is reinforced to give strength thereto and also to afford an air space between the outer and inner surfacesv of the block.

A still further object of the invention is the provision of a building block which is simple in construction, capable of resisting the action of cold and moisture, and also which is inexpensive in manufacture.

With these and other objects in view, the invention consists in the construction, combination and arrangement ofparts as will be hereinafter fully described, illustrated in the accompanying drawing, and pointed out in the claim hereunto appended.

In the drawing z--Figure 1 is a fragmentary perspective view of a wall showing the wall and corner blocks constructed in accordance with the invention. Fig. 2 is a horizontal sectional view through one of the blocks. Fig. 3 is a vertical transverse sectional view thereof. Fig. 4 is a top plan View of one of the wall blocks. Fig. 5 is a top plan view of one of the corner blocks.

Similar reference characters indicate corresponding parts throughout the several views in the drawing.

Referring to the drawing in detail, A designates each of the wall blocks and B the corner blocks.

The wall blocks each comprises cementitious inner and outer slabs 5 and 6 respectively, the same being of uniform width, thickness and length with respect to each other and are arranged in spaced parallel relation to each other. The slabs are joined through the medium of an endless rectangular shaped frame preferably made from angle iron, the longer stretches 7 of which are embedded within the slabs 5 and 6, while the shorter stretches 8, which are at right angles thereto, extend through the inner faces of the slabs and serve to unite the same in spaced relation to each other, the inner4 slab 5 being disposed or longitudinally offset with relation to the outer slab 6 so that one end thereof will extend beyond the end adjacent thereto of the slab 6, while the opposite end of the latter will extend beyond the adjacent end thereof of the said slab 5 so that when the wall blocks are positioned in a row the outer slabs 6 will be disposed in overlapping relation to the inner slabs 5 thereof.

The corner block B comprises spaced parallel slabs 9 and l0 respectively which are united through the medium of an end wall or slab 11, the reinforcin frame havin its longer stretches 19. embe ded in the sla s 9 and 10, while the short stretches 11 intersect the spaces between the slabs 9 and 10 which are arranged in spaced parallel relation to each other.

The inner slab 10 is formed at one corner of the block with a recess 13 in which fits the outer slab 6 adjacent thereto of one of the wall blocks in the row when the same are being positioned in the formation of a building. It will be obvious that by reason of the construction of the block an air space will be afforded between the slabs thereof, and this space constitutes a means for ventilation, and the air in said spaces forms an insulation which prevents frost and moisture from penetrating into the interior of a building.

The reinforcing frames by reason of their l formation in the shape of an angle iron enable the secure anchoring of the longer stretches thereof in the slabs of the block so as to prevent the working loose of the same or the pullinr of the frame from the slabs, as well as affording maximum reinforcing medium therein.

From the foregoing it is thought that the construction and manner of operation of the device will be clearly understood, and therefore a more extended explanation has been omitted.

What is claimed is A block of the class described comprising a pair of slabs arranged in spaced parallel relation to each other, one of the slabs being longitudinally oset with relation to the other slab, and a continuous rectangularshaped frame having its slde bars and a portion of its end bars embedded in the respec- Q missie tive sbs, the said bers of the frame being of substantially IL-shape in cross` section' throughout the extent of the frame whereby the side, bers and portions of the end bars 5 Will be anchored in the slabs to prevent disp placement thereof relative to each other, the

anges provided by the shape in cross secton of the bars being1 of uniform Width throughout, the longer stretches of the frame 10 being` designed to reinforce `and anchor mejor portions of the opposed-slabs, whie the shorter stretches of seid frame serve as cross braces therefor near opposite vextrenriities of the block. c

In testimony whereof We LK our signe- 15 tures in presence of tWo Witnesses.
